besides, in most cases where touch is used in src/sys, what is really
needed is truncate (or :>):
opt_ppp.h:
touch ${.TARGET}
.if ${PPP_BSDCOMP} > 0
echo "#define PPP_BSDCOMP ${PPP_BSDCOMP}" >> ${.TARGET}
.endif
.if ${PPP_DEFLATE} > 0
echo "#define PPP_DEFLATE ${PPP_DEFLATE}" >> ${.TARGET}
.endif
.if ${PPP_FILTER} > 0
echo "#define PPP_FILTER ${PPP_FILTER}" >> ${.TARGET}
.endif
.endif
if for some reason this target should run several times, opt_ppp.h
will end up with multiple definitions of the same macros.
